本文介绍了一种无磁转子的无轴承电机拓扑结构，与以前发表的拓扑结构相比，它提供了更高的转子转矩密度和更宽的磁气隙。通过使用含有永磁体的只有8个齿的定子，使杂散磁通最小化。采用三维有限元模拟方法设计了转子偶极对为6、奇极对为9的实验样机，并对其性能进行了分析。提出了补偿寄生径向力以实现转子稳定磁悬浮的控制方案。实现的原型机达到了2000 rpm的转速和8 Nm的最大扭矩。
This paper introduces a bearingless motor topology with a magnet-free rotor that provides a higher rotor torque density and wider magnetic air gap compared to previously published topologies. The stray flux is minimized by using a stator with only eight teeth in temple configuration that contain permanent magnets. The motor performance is analyzed based on experimental prototypes, that were designed using 3D FEM simulations, for even and odd rotor pole pair numbers of six and nine, respectively. Control schemes that compensate parasitic radial forces to achieve stable magnetic levitation of the rotors are presented. The implemented prototypes reached a rotational speed of 2000 rpm and a maximum torque of 8 Nm.
